High-efficiency electromagnetic reversing pneumatic pump

Abstract

The invention discloses a high-efficiency electromagnetic reversing pneumatic pump. The high-efficiency electromagnetic reversing pneumatic pump comprises an air cylinder body, a piston and a piston rod. The piston is arranged in the air cylinder body and is in sealing sliding fit with the air cylinder body. An inner cavity of the air cylinder body is divided into a rod cavity and a rodless cavitythrough the piston. The piston rod is coaxially fixed to the piston and penetrates out of the air cylinder body in the axial direction. A first ventilation port is formed in the cavity wall of the rodless cavity. A second ventilation port is formed in the cavity wall of the rod cavity. The high-efficiency electromagnetic reversing pneumatic pump has the beneficial effect that an electromagnetic reversing mechanism is arranged between the first ventilation port and the second ventilation port. The high-efficiency electromagnetic reversing pneumatic pump has the beneficial effects that due to the fact that air exchange between the rod cavity and the rodless cavity in the air cylinder body is achieved through the electromagnetic reversing mechanism, a whole pneumatic pump body is small in size, noise is low, the reversing action is fast, and efficiency and precision are high; and in addition, the structure of the electromagnetic reversing mechanism is simple, machining and maintaining are convenient, and cost is low.

Description

technical field

[0001] The invention relates to a pneumatic pump, in particular to a high-efficiency electromagnetic reversing pneumatic pump. Background technique

[0002] The pneumatic pump uses compressed gas as the power source, controls the flow direction of the compressed gas through the reversing mechanism, and the compressed gas drives the cylinder piston to move, and realizes the function of outputting reciprocating linear motion. The core component of the pneumatic pump is the reversing mechanism. The current reversing mechanism mainly includes two types: mechanical type and valve type. The reversing mechanism has high requirements on the spool. The spool in my country is mainly made of alloy aluminum, which is fragile and not durable. However, the high-end spool in foreign countries is expensive, and my country does not have the production technology and production conditions. Contents of the invention

Embodiment 1

[0017] Embodiment 1: As shown in the figure, a high-efficiency electromagnetic reversing pneumatic pump includes a cylinder block 1, a piston 2 and a piston rod 3. The piston 2 is arranged in the cylinder block 1 and is sealed and slidably matched with the cylinder block 1. The piston 2 divides the inner cavity of the cylinder block 1 into a rod cavity 11 and a rodless cavity 12. The piston rod 3 is coaxially fixed with the piston 2 and passes out of the cylinder block 1 in the axial direction. The wall of the rodless cavity 12 is provided with a second A vent 13, a second vent 14 is arranged on the cavity wall of the rod cavity 11, an electromagnetic reversing mechanism is arranged between the first vent 13 and the second vent 14, and the electromagnetic reversing mechanism includes a casing 4 and The guide rail 5, the slide block 6 and the partition 7 arranged in the box body 4, the left and right ends of the guide rail 5 are respectively fixedly provided with strip electroma...

Embodiment 2

[0019] Embodiment 2: As shown in the figure, other structures are the same as Embodiment 1, and the difference is that the first exhaust hole 43 and the second exhaust hole 45 communicate with the upper part of the guide rail 5 in the box body 4 through the air pipe, A pressure sensor 10 is fixed inside the upper end of the box body 4 , and an air intake switch 48 is arranged on the first air pipe 47 .

[0020] In the above embodiment, the working process of the electromagnetic reversing pneumatic pump is as follows: through the first air pipe 47, the box body 4 is fed with air, and then the long electromagnet 8 located at the left end of the guide rail 5 is energized, and the electromagnet 91 located at the left side is energized. Power on, the strip electromagnet 8 absorbs the slider 6 and moves to the left end of the guide rail 5, while the block 9 on the left side is attracted by the electromagnet 91, and the first exhaust hole 43 is opened. At this time, the compressed gas...
